Yeah, talent is Guarded by the Light. Can refresh Divine Plea on hit; full refresh, not like just a couple seconds added on.

I think the change probably had less to do with changes to spirit regen, but probably to give tankadins less need to drink after fights where they didn't need much healing. Sometimes I ran out of mana simply because seals/judgements couldn't keep up with a rotation without a healer providing extra mana (didn't need the heals). One problem that all other tanks don't have to deal with.

Just keep in mind that the spirit mana regen only affects the out-of-casting regen. My priest's while-casting mana regen is exactly the same as it was before the changes. Possibly only a few mp5 off; small enough that I didn't notice any significant change in the number. Just need to do a little more number crunching to find opimizations that I didn't need before. Perhaps something like Renew and small heals might have a better healing coeficient (i.e. more healing for less mana). Depends on spec though.

EDIT: Just wanted to throw out these numbers, the "after" is an approximation, as armory hasn't updated for her and I'm going on memory. Priest before: 735/305 mp5. Priest after: 430/300 mp5. Pretty much same spec for both of those numbers; both totally unbuffed. She's actually about 335 while-casting now with the spirit buff that she didn't have access to before.
